To figure out the tax in any cost, you simply take the original cost, and multiply it by the tax which is written as 0.05, since it's in percent. once you get your answer, take the original cost and add on to the product you calculated before. ex 0.05 * 49.95 = 2.4975, now add the original price to the product: 2.4975 + 49.95 = 52.4475. Now just take your final answer and round it the proper decimal place which is to the hundredths place: $52.45. Therefore your final price is $52.45.
Hope that helps :)
Answer:
Slope = 2
Y intercept = 4
Step-by-step explanation:
This is of the form y = mx + k
where m is the slope
K = y intercept
Answer: Length = 15 inches
Width = 12 inches
Step-by-step explanation:
The painting is rectangular.
Let L represent the length of the painting.
Let W represent the width of the painting.
Area of a rectangle = LW
Marisol is panting on a piece of canvas that has an area of 180 square inches. It means that
LW = 180- - - - - - - - - - -1
The length of the painting is 1 and 1 fourth times the width. It means that
L = 1.25W
Substituting L = 1.25W into equation 1, it becomes
W(1.25W) = 180
1.25W² = 180
W² = 180/1.25
W² = 144
W = √144
W = 12 inches
L = 1.25W = 1.25 × 12
L = 15 inches
Answer:
x = -30
Step-by-step explanation:
x - (-10) = -20
Subtracting a negative is adding
x+10 = -20
Subtract 10 from each side to isolate x
x+10-10 = -20-10
x = -30
I don’t know if this is the answer you are looking for, but try 8x-10+8x-10/4 or 16x-20/4, hope this helps
